When you connect your PC wireless with the AP wireless
- can you access the http://192.168.2.1 from your web browser
- can you access the http://192.168.3.1 from your web browser

in qDD if you long press the 'Network' button and enter 192.168.3.1 and then connect can you access the connected camera?

OSX version is available here: http://dslrdashboard.info/downloads/

Probably you are missing some step from the instructions for multiple routers.
Did you add the manual route to the AP device?

Will test with my D7100. qDD only have control of the movie audio through the properties that are available in camera properties display under the movie category.

Sorry, seams I missed your post.
I already have OpenWrt for MR3020 here with ddserver included:

The params for LV filters are on my TODO list, no timeframe.

Yes I know that the camera can capture with 5 fps but while the camera is controlled over USB/wifi (PTP) it is working a bit different.
The camera will not allow to start a new capture while the started capture is finished (capture + write image to SD card).

I already think about his but had no time yet to try and implement it.
I hope in future version I could add a focus control if LV is active while in LRT.

No you don't need the WinUSB driver if you will only use wireless. It is only needed if you connect your camera with USB.

As far I know it will not work.
Unfortunately there is no documentation for developers from Pentax.
Maybe if they release some or if I get my hands on a Pentax I could add.
